To all whom it-mcty concern: Y

Be it known that I, OTTO NIEHAUS, a citizen of the United States, residing atNVest Berke- 'ley, county of Alameda, State of California, haveinvented an Improvementin Adjustable Window-Screens; and I hereby'declare the 1 following to be af ull, clear, and exact descrip-f tion of the same.

My invention relates to improvements in screens for windows and Isimilar light-aper-" tures, Y

casing in position 'on the window frame, a

ing is drawn, means upon/the opposite side Y of theframe by whicl the'screeningis engage'd, adjustable .lateral guides for said screening, ineansfor adjusting the-tension of Y the sprin'g'in the roller, and includes details ings, in which' p H I Figure 1 is a frontviewof,my-screcn attached to window-frame: Fig. 2 is'a horizontal section takenont'he line 'y y of'Fig. 1.

which will be more fully set forth hereinafter;- having reference to th'e accompanyin g dr'aw-' Fig. 3 is a central section of case, taken onthe tiveviewshowing onewayof supportingtele-v scopic guides. Fig. 6 is, a perspective view line w roof Fig. 4." Fig.4 is a cross-section on the lines ,2 ofFig. 3. Fig. 5 is a perspecshowing manner'of holding screening.

. Arepresents a suitable casing in which the I screen-roller 2,carrying the screening 3,is contained. The roller is freely turnable about I a central shaft 4. One end of the latter pro-,

Y jects beyond the roller and is flattened andadapted to fit in a slot'5 inthe end ofv the casing, whereby the shaft is prevented from turning.- The other end of the roller is provided 'with a trunnion 4, turnable in a recess in the end of the casing. A spring 5 is attached terior of the tube by'remoying the cap 7.

Y at one end tothe shaft within the roller-tube,

and the other end of the spring is secured in a slot 6 inthe tube. Access is had to the inis to be noted that the usual pawl-an'd-ratchet. mechanism is omittedin. thisidevice, so that the screening is freely wound upon or unwound fromthe roller. The roll is prevented from falling out of the casing by means of a I A flexible. screening carried upon a spring-roller, a. casing in which the roller is supported, meansfor attaching the spring. Y p 1 {The casing'A hasthe longitudinal slots 11 gfo'rm'edin one side.v Y Theiowei" end of these pin 8, whichretains the flattened end of the -shaft in the slot 5.1 The cap 7 is'radiallyper- @forated, as at 9, and a perforation'lO in the shaft 4 is adapted toregister with the'perfofration 9 when the tube is turned about the fshaft. Y When'itis desir'edto remove the roll ;fromthe casin'g,'the pin SQis ithdraWn from ;its place across the slot 5 and iuserted'in' the perforations QandlO, which are brought into :linefor thepurpose, to lock the tube and shaft ,f'together'and prevent the unwinding of the slots is enlarged, a's-at 12, through whiclrthe i 'head'of a-n'ail or screw 19 may pass; The

upper portion of the slots is narrowed, so that. 1

shank of thenailhas slipped up .into the slot. Y I Thiscasing is ordinarily h'ung on the side of Y the frame and adjacent to'the Window-sash. l 'The fendof thescreeningpassesthrougli a longitudinal slotl3 inthecasing and attached Y toa bar Li -having a knob orhandle 15, by Y the'head may not be withdrawn after the,

which the bar maybe engaged and'moved across the-window-opening. O'n-the'under side-0f the bar is a curved flange or hoofk 16,

which is adapted to engage some means upon the'frame on the opposite side of the window and hold the screen" When-the latter is stretched thereacross This means consists of a bar 17,h'aving slots 18, similarto the.

slots 11, by which'the' bar} is removably se-,

cured (to the screws or nails 19. A metal Y flange 20 is secured to one edge ofthe bar 17 and is provided with a turned-over hook portion 21, with whichithe hook 16 of the screenbar 14 engages. A

In order to support the edgesjof the screening when it isstretched across the window, I

provide :the: telescoping lateral 'g uides 22,

which readily adjust themselves .to difierent widths of windows. These guides are pivoted to the casing at 23 and when closed up are approximately of 'a length equal to the casing, so that the devicemaybeknocked down and folded into a small compactpack "age for purposes of transportation. The'slidable part of each guide has a lug 24, by which it may be drawn in or out of thepivoted: sheath portion of the guide. The bar 17 is suitably recessed at its ends and'on its edge LII adjacent to the flange 20, as at 25, in order to admit and hold the ends of the guides.

It is necessary that both the casing and bar 17 be hung properly in relation to each other. To assist in the proper location of the nails 19 19, I have formed certain guide-notches 26 in the edge of the bar 17. This bar is first placed against the vertical portions of the window-frame to which the two parts of the device are to attach with the enlargement 12 of the slots 11 uppermost and the end of the bar resting on the window-sill. The position of the notches 26 indicate the exact point at which the nails should be driven. Having located the position for the nails, the guide is removed and the nails then driven in, after which the casing and bar may be hung thereon in proper position, as before described, with the enlarged portions 12 12 of the slots lowermost.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. An adjustable window-screen consisting of a spring-actuated screen-roll, means for attaching it on one side of a window-frame, means upon the opposite side of the frame by which the screening maybe engaged and held in opposition to the spring, and laterally-ad:

just'able bars connecting the bar at one side of the window-opening with the roller-support at the opposite side.

2. An adjustable window-screen,consisting of a casing a spring-actuated screen-roll journaled therein, said casing adapted to be secured upon one side of the window-frame, means upon the opposite side of the frame by which the end of the screening may be engaged and held in opposition to the spring, and upper and lower folding bars connecting the bar at one side of the opening with the roller-casing at the opposite side.

3. In an adjustable window-screen the combination of a casing, a hollow roller having a central shaft projecting from one end and about which said roller is turnable, a slot in said roller a spring secured at one end to the shaft and the other end fixed in said slot, a cap through which the shaft passes, said cap fixed to and turnable in unison with the roller, perforations in the cap and shaft, a pin adapted to be passed through said perforations whereby the tube and shaft may be locked together,and the former prevented from turning, a flexible screening wound upon said roller, and bars pivotally connected to the casing and adapted to extend transversely across the window-0pening, and a bar attached to the screening and with which the transverse bars are adapted to connect.

1, The combination in an adjustable window-screen of a casing, a spring-actuated screen roller therein, means for attaching said casing to the side of a window-frame, a slot in said casing through which the screening is drawn, a bar exterior to the casing and to which the end of said screen is attached,

means upon the opposite side of the windowframe by which said bar may be engaged and the screen .held in opposition to the tension of the spring, and pivotally-mounted longitudinally-extensible bars adapted to connect the bar at one side of the window-opening with the roller-casing at the opposite side.

5. The combination of a flexible screening, a spring actuated roller upon which said screening is carried, a movable support for said roller, said support adapted to be detachably secured to a window-frame, means upon the opposite side of said frame with which the end of said screening may be engaged, said means consisting of a bar having a flange projection thereon, and adjustable lateral guides connecting said bar and rollersupport.

ln'witness whereof I have hereunto set my hand.

OTTO NIE I-IAUS.
